Description

Shock absorption and isolation test platform for high polymer material sliding plate

Technical Field

The utility model belongs to the technical field of subtract the shock insulation testing machine, especially, relate to a macromolecular material slide subtracts shock insulation test platform.

Background

In the preparation process of the high polymer material sliding plate, in order to test the seismic isolation and reduction performance of the high polymer material sliding plate, a seismic isolation and reduction test is carried out by using a high polymer material sliding plate seismic isolation and reduction test platform. The existing seismic isolation and reduction testing machine comprises a frame body, a lower die fixed with the frame body, an upper die and a push-pull cylinder which are connected with the frame body through a lifting cylinder, a testing slide block of which the tail part is connected with the push-pull cylinder is arranged between the upper die and the lower die, the upper surface and the lower surface of the testing slide block are friction surfaces, a high polymer material slide plate to be tested is placed in the upper die and the lower die, and the high polymer material slide plate is rubbed through the front-back movement of the testing slide block to calculate the friction coefficient. The shock absorption and isolation test platform for the high polymer material sliding plate has the following defects: firstly, a first connecting frame is fixed at the front end of a mandril of the push-pull air cylinder, two connecting columns are arranged on the connecting frame, a second connecting frame with a through hole is arranged behind the test slider, and the connecting columns are inserted into the through hole; secondly, in the high-speed motion process of the test slider, the test slider is inclined and deviates easily due to uneven pressure, uneven material of the high polymer material sliding plate and the like.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is exactly to provide a long service life, can not cause the high molecular material slide that experimental slider and support body striking, noise are little, test data are more accurate subtract shock insulation test platform.

In order to solve the above problem, the utility model discloses the technical scheme that macromolecular material slide subtracts isolation test platform adopted does: the testing device comprises a frame body, a lower die fixed with the frame body, an upper die and a push-pull cylinder, wherein the upper die and the push-pull cylinder are connected with the frame body through a lifting cylinder, a testing slide block with the tail connected with the push-pull cylinder is arranged between the upper die and the lower die, the upper surface and the lower surface of the testing slide block are friction surfaces, a guide rail is arranged on the frame body in front of the testing slide block, a guide block is arranged in front of the testing slide block, a guide groove is arranged below the guide block, and the guide rail is inserted into the guide groove.

The additional technical characteristics are as follows:

the cross section of the guide rail is I-shaped, and the guide groove is rectangular with an opening at the lower part;

and a ball frame with balls is arranged in the guide groove.

The utility model provides a macromolecular material slide subtracts isolation test platform compares with prior art, has following advantage: the testing device comprises a frame body, a lower die fixed with the frame body, an upper die and a push-pull cylinder, wherein the upper die and the push-pull cylinder are connected with the frame body through a lifting cylinder; secondly, as the section of the guide track is I-shaped, the guide groove is rectangular with an opening at the lower part; in the moving process of the test sliding block, the moving direction cannot be changed, the test sliding block cannot be inclined, and the test data are more accurate; thirdly, because the guide groove is internally provided with the ball frame with the balls, the friction coefficient is reduced, and more energy is saved.
